Polyester fiber and non-woven needled felt filtration material made
of it

Polyester needled filtration felt is made by polyester fiber and
the fabric woven high-strength, low-elongation yarn. The Dacron
fibers are needled noto the fabric by needled-punching machine.

Polyester fiber has low absorption of humidity. The water regain
rate under standard condition is 0.4-0.5%,while 0.6-0.8% under the
condition of relative humidity 100%. Therefore, the fiber will keep
almost the same properties in both dry and wet conditions. It shows
good resistance for almost all the atmosphere under the room
temperature.

The strength of the polyester is high and the elastic recovery
performance is good. The strength of it is 3.52-5.28CN/dtex,
elongation at break is around 30-40%.

The polyester has good size stability, high strength, high
elongation and good elastic recovery performance. So that, the
polyester fabrics fabrics has good abrasion resistance.

The glass transition point of polyester fiber is 80℃,melting point
is 255℃~265℃. It starts to become soft at 230℃~240℃. Polyester
fiber has very good application function under room temperature. It
is the most reasonable filtration materials for the industry
conditions with common temperature.

This product has the advantages of high porosity, good
permeability, good abrasion resistance and resistance to acid. The
consumption amount of polyester is the biggest among the needled
felt filtration material. It is widely used in the fields of
metallurgical, chemical, building materials, metallurgy, power
generation, ceramics, machinery, mining, petroleum, pharmaceutical,
food, dye, mining etc. It is currently the most ideal filtration
materials for the common temperature conditions.

Hangzhou philis filter technology co.,ltd. has grown up to be one of leading manufacturer on dust
filtration&spare parts in China.We have imported filter needle
felt production line ASSELIN from France and we can produce very
good quality non-woven products according customer's requirment.

Based on 8 needle felt production line ,our annual production
ability can achieved 20,000 square meters per day . We can produce
a large range of various filter fabric, such as polyester filter
fabric, Acrylic filter fabric, Fiberglass filter fabric, PPS filter
fabric, Nomex ,P84 ,PTFE ,woven filter fabric and so on.

The most important thing is that we introduced German high
technology to develop the first filter bag production line in
China. Which help most filter bag production factory save a lot of
human lab our cost but promote the work effection . The advanced
technology and simple operation way of automatic filter bag
production line has won a lot of customer’s praise.
